BRAKE DEVlCE FOR GUNS.

SPECIFICATION formingpart of Letters Patent No. 635,573, dated October 24, 1899.

Application filed December 16, 1898- berial No. 699,499. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDUARD Mi'ILLER, a citizen of Switzerland, residing at Thun, Switzerland, have invented certain new and useful Improvements in Brake Devices for Guns or Cannon, of which the following is a specification.

This invention relates to guns and cannon, and has more particular reference to brake devices therefor, the object being to provide a device adapted to be operated by the action of the back impact produced by the shot, so that the anchorage, the stopping of the backward movement, the forward movement, and the releasing of the gun or cannon will be automatically produced, said gun or cannon being always released from the ground and ready for aiming and setting.

\Vith this object in view'my invention consists of pivotally-mounted braces adapted to be driven into the ground by reason of the inertia of their gravity, combined with the backward movement of the gun or cannon. This backward movement is stopped and the forward movement promoted on the one hand by the action of suit-able elastic devices, such as springs, the tension of which being increased in the backward movement by the rotation of the braces to store up the neces sary amount of power for producing the forward movement and on the other hand by the raising of the center of gravity of the gun or cannon occurring in the backward movement thereof and the lowering of said center of gravity produced by the weight of the gun or cannon. The removal of the anchorage-2'. e., the withdrawing of the braces from the groundis also effected by the releasing of the aforesaid elastic device in the forward movement of the gun or cannon.

In the accompanying drawings, Figure l is a side elevation of a gun or cannon provided with my improvements, the left-hand wheel being removed. Fig. 2 is a top plan view of the gun or cannon. Fig.3 shows in side elevation the improved brake device in operation. Fig. 4 shows in side elevation the gun or cannon with the improved brake device in an inoperative position. Fig. 5 is a side elevation of a gun or cannon provided with a slightly-modified brake device. Fig. 6

shows the modified brake device in operation.

In the drawings like letters refer to like parts throughout all the figures.

The improvements consist of legs or braces S S, arranged on each side of the gun or cannon and loosely or pivotally attached at cl d to the axle A of the frame or carriage. The lower or knee portion of said braces is provided with a small pointed lug orspur k and with a larger spur g at the end, said spurs being rearwardly inclined and adapted to be driven into the ground and prevented from penetrating too far into the ground by the width of the body of the braces. Each brace S has a pivot-pin b, Fig. 1, flexibly connected by means of a rearwardly extending chain C, running parallel with and on the outside of the corresponding trail, with the pivot-pin c in the lower end of a double-arm lever h. Said lever 7b is rotatable on a shaft 0, journaled in the trail, and the upper end of said lever pivotally attached at 2' to a gnide-rod Z) I), the rear end of which extends loosely lhrough an eye Z, having trunnions m journaled in the trail of the cannon. The fore end of said guide-rod carries a nut m, by means of which the tension of the coilspring F, fitted over said rod and having its upper end bearing against said nut and its lower end bearing against said eye Z, may be adjusted as required. The movement of the lever h in the direction of the arrow at c, Fig. 1, is limited by a suitable stop-lug 02,10- cated on the lower part of the trail. The minimum tension of said spring F will correspond to the pressure produced on said spring by the rotation of the free ends or soles of braces S in the direction of the arrow at 75, said pressure being transmitted through the agency of chain C, double-arm lever h, and screw-nut m. The cannon being ready for shooting, the lugs or spurs 76 and 9 do not engage the ground, as in Fig. 1, the attachment of the braces S being regulated so as to leave a distance of about two to four inches between lugs and the ground.

- The operation of the device is as follows: The shot produces on the gun-barrel firmly connected with the trail a violent recoil. The

braces S on account of their weight tend to No- 635,598. Patented 00%. 24, !899.
